Chiral Symmetry Breaking and the Masses of Hadrons: A Review

Symmetry, 2023
The masses of hadrons in the vacuum, where the chiral symmetry is restored, and in the medium are generally different even when the changes in the order parameters of chiral symmetry are the same.

Crystallization-driven template autocatalysis induces mirror symmetry breaking and amplification [PDF]

Nature Communications
A plausible hypothesis for the origin of biological homochirality invokes chiral symmetry breaking, transfer, and amplification driven by autocatalysis. Here we experimentally demonstrate that crystallization-driven template autocatalysis (CDTA) induces ...

Minimally doubled fermions and spontaneous chiral symmetry breaking

EPJ Web of Conferences, 2018
Chiral symmetry breaking in massless QCD is a very important feature in the current understanding of low energy physics. Low - lying Dirac modes are suitable to help us understand the spontaneous chiral symmetry breaking, since the formation of a non ...

Left-right symmetry breaking: learning from the chicken [PDF]

Frontiers in Cell and Developmental Biology
Morphological left-right asymmetry of visceral organs in most cases reveals a typical arrangement. This implies directed symmetry breaking which is suggested to be based on the existence of structural chirality.

Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows

Nature Communications, 2022
External physical forces can bias a spontaneous symmetry breaking process but whether the shape of a reactor plays a role in chiral symmetry breaking processes is an open question. Here, the authors demonstrate chirality transfer from the chiral shape of

Interplay between nuclear chiral and reflection symmetry breakings revealed by the lifetime measurements in 76Br

Physics Letters B, 2022
Nearly degenerate positive-parity doublet bands and several E1 transitions between positive- and negative-parity bands have been identified in 76Br. These experimental observations are interpreted as the coexistence of chirality and octupole correlations,

A Skyrme Model with Novel Chiral Symmetry Breaking [PDF]

, 2023
An extension of the Skyrme model is presented in which derivative terms are added that break chiral symmetry to isospin symmetry. The theory contains just one new parameter and it reduces to the standard Skyrme model when this symmetry breaking parameter

Gapped Chiral Fermions

Physical Review X, 2021
In principle, there is no obstacle to gapping fermions preserving any global symmetry that does not suffer a ’t Hooft anomaly. In practice, preserving a symmetry that is realized on fermions in a chiral manner necessitates some dynamics beyond simple ...

Non-Abelian anomalous constitutive relations of a chiral hadronic fluid [PDF]

EPJ Web of Conferences, 2022
We study the constitutive relations of a chiral hadronic fluid in presence of non-Abelian’t Hooft anomalies. Analytical expressions for the covariant currents are obtained at first order in derivatives in the chiral symmetric phase, for both two and ...

Nambu–Jona-Lasinio model in a parallel electromagnetic field

Physics Letters B, 2018
We explore the features of the UA(1) and chiral symmetry breaking of the Nambu–Jona-Lasinio model without the Kobayashi–Maskawa–'t Hooft determinant term in the presence of a parallel electromagnetic field. We show that the electromagnetic chiral anomaly
